SAFETY
SAFETY FEATURES
ANTI-LOCK BRAKE SYSTEM (ABS)
The ABS provides increased vehicle stability and brake
performance under most braking conditions. The system
automatically prevents wheel lock and enhances vehicle
control during braking.
The ABS performs a self-check cycle to ensure that the
ABS is working properly each time the vehicle is started
and driven. During this self-check, you may hear a slight
clicking sound as well as some related motor noises.
The ABS is activated during braking when the system
detects one or more wheels are beginning to lock. Road
conditions such as ice, snow, gravel, bumps, railroad
tracks, loose debris, or panic stops may increase the
likelihood of ABS activation(s).
You also may experience the following normal
characteristics when the ABS activates:
ABS motor noise or clicking sounds (you may continue
to hear for a short time after the stop).
 Brake pedal pulsations.
 A slight drop of the brake pedal at the end of the stop. The ABS is designed to function with the Original
Equipment Manufacturer (OEM) tires. Modification may
result in degraded ABS performance.
Anti-Lock Brake System (ABS) Warning
Light
The yellow ABS Warning Light will turn on when the ignition
is placed in the ON/RUN mode and may stay on for as long
as four seconds.
If the ABS Warning Light remains on or comes on while
driving, it indicates that the anti-lock portion of the brake
system is not functioning and that service is required.
However, the conventional brake system will continue to
operate normally if the ABS Warning Light is on.
If the ABS Warning Light is on, the brake system should be
serviced as soon as possible to restore the benefits of
Anti-Lock Brakes. If the ABS Warning Light does not come
on when the ignition is placed in the ON/RUN mode, have
the light repaired as soon as possible.
WARNING!

The ABS contains sophisticated electronic equip -
ment that may be susceptible to interference caused
by improperly installed or high output radio transmit -
ting equipment. This interference can cause possible
loss of anti-lock braking capability. Installation of
such equipment should be performed by qualified
professionals.
 Pumping of the Anti-Lock Brakes will diminish their
effectiveness and may lead to a collision. Pumping
makes the stopping distance longer. Just press firmly
on your brake pedal when you need to slow down or
stop.
 The ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that afforded
by the condition of the vehicle brakes and tires or the
traction afforded.
 The ABS cannot prevent collisions, including those
resulting from excessive speed in turns, following
another vehicle too closely, or hydroplaning.
The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous
manner that could jeopardize the user’s safety or the
safety of others.

SAFETY241
ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
Your vehicle is equipped with an advanced EBC system.
This system includes the Anti-Lock Brake System (ABS),
Brake Assist System (BAS), Electronic Brake Force
Distribution (EBD), Electronic Stability Control (ESC),
Electronic Roll Mitigation (ERM), Hill Start Assist (HSA),
Intersection Collision Assist (ICA), and Traction Control
System (TCS). These systems work together to enhance
both vehicle stability and control in various driving
conditions.
Your vehicle may also be equipped with Dynamic Steering
Torque (DST), Rain Brake Support (RBS), Ready Alert
Braking (RAB), and Trailer Sway Control (TSC).
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sensing
the rate and amount of brake application and then applies
optimum pressure to the brakes. This can help reduce
braking distances. The BAS complements the Anti-Lock
Brake System (ABS). Applying the brakes very quickly
results in the best BAS assistance. To receive the benefit
of the system, you must apply continuous braking
pressure during the stopping sequence (do not “pump”
the brakes). Do not reduce brake pedal pressure unless
braking is no longer desired. Once the brake pedal is
released, the BAS is deactivated.
Brake System Warning Light
The red Brake System Warning Light will turn on when the
ignition is placed in the ON/RUN mode and may stay on for
as long as four seconds.
If the Brake System Warning Light remains on or comes on
while driving, it indicates that the brake system is not
functioning properly and that immediate service is
required. If the Brake System Warning Light does not
come on when the ignition is placed in the ON/RUN mode,
have the light repaired as soon as possible.
Electronic Brake Force Distribution (EBD)
EBD manages the distribution of the braking torque
between the front and rear axles by limiting braking
pressure to the rear axle. This is done to prevent
overslip of the rear wheels to avoid vehicle instability, and
to prevent the rear axle from entering ABS before the
front axle.
Electronic Roll Mitigation (ERM)
ERM anticipates the potential for wheel lift by monitoring
the driver’s steering wheel input and the speed of the
vehicle. When ERM determines that the rate of change of
the steering wheel angle and vehicle’s speed are
sufficient to potentially cause wheel lift, it then applies the
appropriate brake and may also reduce engine power to
lessen the chance that wheel lift will occur. ERM can only
reduce the chance of wheel lift occurring during severe or
evasive driving maneuvers; it cannot prevent wheel lift
due to other factors, such as road conditions, leaving the
roadway, or striking objects or other vehicles.
NOTE:
ERM is disabled any time the ESC is in “Full Off” mode (if
equipped). See
Úpage 242 for a complete explanation of
the available ESC modes.
WARNING!
The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing road
conditions. BAS cannot prevent collisions, including
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. The
capabilities of a BAS-equipped vehicle must never be
exploited in a reckless or dangerous manner, which
could jeopardize the user's safety or the safety of
others.
WARNING!
Many factors, such as vehicle loading, road conditions
and driving conditions, influence the chance that wheel
lift or rollover may occur. ERM cannot prevent all wheel
lift or rollovers, especially those that involve leaving the
roadway or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must never be
exploited in a reckless or dangerous manner which
could jeopardize the user's safety or the safety of
others.

270SAFETY
The Air Bag Warning Light in the instrument
panel will turn on whenever the OCS is unable
to classify the front passenger seat status.
A malfunction in the OCS may affect the
operation of the air bag system.
If the Air Bag Warning Light does not come on,
or stays on after you start the vehicle, or it
comes on as you drive, take the vehicle to an
authorized dealer for service immediately.
The passenger seat assembly contains critical OCS
components that may affect the Passenger Advanced
Front Air Bag inflation. In order for the OCS to properly
classify the seated weight of a front seat passenger, the
OCS components must function as designed. Do not make
any modifications to the front passenger seat
components, assembly, or to the seat cover. If the seat,
trim cover, or cushion needs service for any reason, take
the vehicle to an authorized dealer. Only FCA US LLC
approved seat accessories may be used.
The following requirements must be strictly followed:
 Do not modify the front passenger seat assembly or
components in any way.
 Do not use prior or future model year seat covers or
cushions not designated by FCA US LLC for the specific
model being repaired. Always use the correct seat
cover and cushion specified for the vehicle.
 Do not replace the seat cover or cushion with an after -
market seat cover or cushion. 
Do not add a secondary seat cover or mat.
 At no time should any Supplemental Restraint System
(SRS) component or SRS related component or
fastener be modified or replaced with any part except
those which are approved by FCA US LLC.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the
driver and front passenger, and position the front
occupants for improved interaction with the front air bags.
Supplemental Driver And Front Passenger
Knee Air Bags
This vehicle is equipped with a Supplemental Driver Knee
Air Bag mounted in the instrument panel below the
steering column and a Supplemental Passenger Knee Air
Bag mounted in the instrument panel below the glove
compartment. The Supplemental Knee Air Bags provide
enhanced protection during a frontal impact by working
together with the seat belts, pretensioners, and front
air bags.
Supplemental Side Air Bags
Supplemental Seat-Mounted Side Air Bags (SABs)
This vehicle is equipped with Supplemental Seat-Mounted
Side Air Bags (SABs).
Supplemental Seat-Mounted Side Air Bags (SABs) are
located in the outboard side of the front seats. The SABs
are marked with “SRS AIRBAG” or “AIRBAG” on a label or
on the seat trim on the outboard side of the seats.
WARNING!
Unapproved modifications or service procedures to
the passenger seat assembly, its related compo -
nents, seat cover or cushion may inadvertently
change the air bag deployment in case of a frontal
collision. This could result in death or serious injury
to the front passenger if the vehicle is involved in a
collision. A modified vehicle may not comply with
required Federal Motor Vehicle Safety Standards
(FMVSS) and/or Canadian Motor Vehicle Safety
Standards (CMVSS).
 If it is necessary to modify the air bag system for
persons with disabilities, contact an authorized
dealer.
WARNING!
Do not drill, cut, or tamper with the knee impact
bolsters in any way.
 Do not mount any accessories to the knee impact
bolsters such as alarm lights, stereos, citizen band
radios, etc.

SAFETY271
The SABs may help to reduce the risk of occupant injury
during certain side impacts, in addition to the injury
reduction potential provided by the seat belts and body
structure.

Front Supplemental Seat-Mounted Side Air Bag Label

When the SAB deploys, it opens the seam on the outboard
side of the seatback’s trim cover. The inflating SAB
deploys through the seat seam into the space between the
occupant and the door. The SAB moves at a very high
speed and with such a high force that it could injure
occupants if they are not seated properly, or if items are
positioned in the area where the SAB inflates. Children are
at an even greater risk of injury from a deploying air bag. Supplemental Side Air Bag Inflatable Curtains (SABICs)
This vehicle is equipped with Supplemental Side Air Bag
Inflatable Curtains (SABICs).
Supplemental Side Air Bag Inflatable Curtains (SABICs)
are located above the side windows. The trim covering the
SABICs is labeled “SRS AIRBAG” or “AIRBAG.”
Supplemental Side Air Bag Inflatable Curtain (SABIC)
Label Location

SABICs may help reduce the risk of head and other injuries
to front and rear seat outboard occupants in certain side
impacts, in addition to the injury reduction potential
provided by the seat belts and body structure.
The SABIC deploys downward, covering the side windows.
An inflating SABIC pushes the outside edge of the
headliner out of the way and covers the window. The
SABICs inflate with enough force to injure occupants if
they are not belted and seated properly, or if items are
positioned in the area where the SABICs inflate. Children
are at an even greater risk of injury from a deploying
air bag. The SABICs may help reduce the risk of partial or complete
ejection of vehicle occupants through side windows in
certain side impact events.
Side Impacts
The Side Air Bags are designed to activate in certain side
impacts. The Occupant Restraint Controller (ORC)
determines whether the deployment of the Side Air Bags
in a particular impact event is appropriate, based on the
severity and type of collision. The side impact sensors aid
the ORC in determining the appropriate response to
impact events. The system is calibrated to deploy the Side
Air Bags on the impact side of the vehicle during impacts
that require Side Air Bag occupant protection. In side
impacts, the Side Air Bags deploy independently; a left
side impact deploys the left Side Air Bags only and a
right-side impact deploys the right Side Air Bags only.
WARNING!
Do not use accessory seat covers or place objects
between you and the Side Air Bags; the performance
could be adversely affected and/or objects could be
pushed into you, causing serious injury.
WARNING!

Do not mount equipment, or stack luggage or other
cargo up high enough to block the deployment of the
SABICs. The trim covering above the side windows
where the SABIC and its deployment path are located
should remain free from any obstructions.
 In order for the SABICs to work as intended, do not
install any accessory items in your vehicle which
could alter the roof. Do not add an aftermarket
sunroof to your vehicle. Do not add roof racks that
require permanent attachments (bolts or screws) for
installation on the vehicle roof. Do not drill into the
roof of the vehicle for any reason.

316SERVICING AND MAINTENANCE
CHECKING OIL LEVEL — 3.0L ENGINES
The 3.0L engine does not have a traditional “dipstick” and
there is no need to manually check the oil level. If it is
desired to check engine oil level, it can be seen on the
instrument cluster display by navigating to the appropriate
screen under “Vehicle Information”. Use the up or
down arrow buttons within the steering wheel controls
to find the “Vehicle Information” menu. Then use the
right or left arrow buttons until you reach the “Oil
Level” sub-menu.
There is a white bar on the gauge which shows the oil level.
As long as the oil level is between the minimum and the
maximum it is safe to operate the vehicle. If the oil level is
either too high or too low, a red bar will be illuminated.
When the engine is in need of more oil, the Oil Level
Warning Light will illuminate. This warning will appear for
five seconds. Within the next 300 miles (500 km) you
should add 1 quart of manufacturer specified motor oil to
the engine
Úpage 376. This light will reappear every time the engine is started
until a safe level is detected. Continuing to operate the
vehicle without adding oil may result in a critically low oil
level and possible engine damage (see “Critically Low”
below).
NOTE:Use care when filling under hood fluids such as engine oil,
washer fluid, antifreeze, etc. to minimize spillage onto top
of engine. Any excess fluid that is spilled onto the top of
the engine should be removed using compressed air or an
absorbent cloth.
Oil Level Display - How To Refresh After Adding Oil
In vehicles equipped with the 3.0L engine, the oil level is
automatically monitored when the vehicle is parked on a
level surface, the oil is warm, and the engine has been off
four minutes. To refresh the oil level display (after a quart
of the correct oil has been added), follow this process:

Run the engine until the oil temperature is above
120°F (49°C).
 Park the vehicle on relatively level ground. 
Turn the engine off and wait four minutes. If you choose
to stay in the vehicle and want to listen to the radio
while waiting, it is acceptable to have the ignition
switch in any position (OFF or ON/RUN) as long as the
engine is not running.
 Start the engine and the new oil level will be available
in the Vehicle Information menu (accessible via the
navigation buttons on the steering wheel).
NOTE:
If the level indication is not updated after the previously
described procedure, repeat. The oil level measure -
ment is made every time the engine has been turned
off (after being warmed up) and on a level surface. If
you do not get a “new” reading after adding oil, find a
more “level” surface to measure. Most parking lots and
gas stations are sufficiently level, some driveways are
not.
 If you have added a quart of oil and the indicator is not
reading 3/4 or full, please contact an authorized dealer
for service.

WARNING!
Be aware the oil cap may be hot. Please use suitable
gloves. WARNING: risk of burns!
CAUTION!
Do not to add too much oil. Overfilling the oil may
damage the engine.

23_WS_OM_EN_USC_t.book Page 316

SERVICING AND MAINTENANCE317
NOTE:
After adding oil to the engine, always reinstall the oil
cap securely by rotating clockwise until it stops. Never
run the engine without the oil fill cap as this could
cause an oil leak.
 Because the oil level is automatically detected only
when the engine has been off and restarted (after four
minutes), the system cannot immediately detect a
sudden drop in oil level while driving (for example, if the
oil pan starts to leak due to damage during an off-road
event).
CHECKING OIL LEVEL — 5.7L & 6.4L
E
NGINES
To ensure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop. The best time to
check the engine oil level is about five minutes after a fully
warmed up engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings.
There are four possible dipstick types:
 Crosshatched zone.
 Crosshatched zone marked SAFE.
 Crosshatched zone marked with MIN at the low end of
the range and MAX at the high end of the range.
 Crosshatched zone marked with dimples at the MIN
and the MAX ends of the range.
NOTE:Always maintain the oil level within the crosshatch
markings on the dipstick.
Adding 1 qt (1 L) of oil when the reading is at the low end
of the dipstick range will raise the oil level to the high end
of the range marking.
ADDING WASHER FLUID
The instrument cluster display will indicate when the
washer fluid level is low. When the sensor detects a low
fluid level, the Low Washer Fluid Warning Light will turn on
and the "Washer Fluid Low" message will be displayed.
The fluid reservoir for the windshield washers and the rear
window washer is shared. The fluid reservoir is located in
the engine compartment, be sure to check the fluid level
at regular intervals. Fill the reservoir with windshield
washer solvent only (not radiator antifreeze). When
refilling the washer fluid reservoir, take some washer fluid
and apply it to a cloth or towel and wipe clean the wiper
blades, this will help blade performance. To prevent
freeze-up of your windshield washer system in cold
weather, select a solution or mixture that meets or
exceeds the temperature range of your climate. This rating
information can be found on most washer fluid containers.
NOTE:Use care when filling under hood fluids such as engine oil,
washer fluid, antifreeze, etc. to minimize spillage onto top
of engine. Any excess fluid that is spilled onto the top of
the engine should be removed using compressed air or an
absorbent cloth.
CAUTION!
If the “Critically Low or Critically High” Oil Level Warning
Light is illuminated, the following steps should be
taken:
Critically Low: add two quarts of manufacturer speci -
fied oil as soon as possible
Úpage 376. Continuing
to operate the vehicle with “Critically Low” oil level
may damage the engine.
 Critically High: contact an authorized dealer for
service. Continuing to operate the vehicle with “Criti -
cally High” oil level may damage the engine.
Do not use any oils that are not manufacturer specified
and API approved.
Used engine oil and oil filters contain substances which
are harmful to the environment. When oil and filters are
changed contact an authorized dealer and dispose of in
a safe and responsible manner.
WARNING!
Commercially available windshield washer solvents are
flammable. They could ignite and burn you. Care must
be exercised when filling or working around the washer
solution.
